A couple entertained their family with a fun science class gender reveal.

Soon-to-be first time parents Kaye Villanizo, 20, and Felix Dignadice, 22, prepared the unique party to celebrate the pregnancy in Davao de Oro province, the Philippines on October 25.

With the help of a chemist relative, the excited pair mixed substances on a pitcher of water which later turned into bright pink.

Footage shows mum Kaye mixing the liquid together with husband Felix until it changed colour.

Kaye said: ‘Everyone cheered with us. I always wanted to have a baby girl. Now, we are only a few months away from seeing each other.'

She added it was her brother-in-law Kevin who prepared the amazing reveal for them.

She said: ‘Kevin is a chemist and we had the idea to ask him for help preparing the unique party. It went well and everyone was so happy to celebrate with us.'
